Bahhaaaa! I know I've told this one before but it brings back memories of MY true story similar to this one.

Got up way early driving 60 miles through a very straight, empty, desert road with hubby. At dark thirty, just as the sun was rising, all was so quiet in the car, just the hum of the engine and so peaceful UNTIL...a VOICE from the BACK SEAT said in a booming voice, "Good Morning!". We both jumped, I slammed on the brakes, we both looked at the back seat only to discover NO one there. After a few moments, we discovered the startling reason why the disembodied voice was coming from our back seat. I had left the radio ON, but the station didn't come on air until sunrise, and I had tuned all the speakers to only be in the rear of the car (like to listen from behind my head so I can hear passengers talking) and this was the Radio Host saying his opening good morning greeting! Next time, gonna wear adult diapers.
